We report here the long-term toleration of treatment with a highly purified human leukocyte alpha-interferon (Interferon Alfanative) in patients with midgut carcinoid tumours with liver metastases. During an 18-month period, 13 consecutive patients with this diagnosis commenced treatment with a-interferon. Five patients died during the first 2 years of treatment due to tumour progression, and in 2 patients the treatment with a-interferon had to be stopped due to severe adverse effects (mainly joint pain and tiredness). Hence, 6 patients tolerated the treatment for a long-term period (greater than 2 years), and in these patients the treatment has continued for more than 3 years; in 3 of them for more than 4 years. In these 6 patients, adverse effects of mild or moderate degree have been observed in 2 patients: itching and hair loss in one and joint pain and hair loss in another. Except for a significant reduction in the blood number of WBC and thrombocytes (although in no patient did leukocytopenia or thrombocytopenia develop) and the development of hypothyroidism in one patient, no biochemical tests have shown significant changes during the long-term treatment. In these 6 patients, objective tumour regression has been observed in 2 patients, stable disease in 3 patients and progression in 1 patient. We conclude that, of the patients initiated on treatment with a-interferon for midgut carcinoids with liver metastases, only approximately 50% are still on the treatment after 2 years. These patients, on the other hand, may continue for a longer period of time with a low degree of adverse effects.

The National Biotherapy Study Group (NBSG) conducted a broad phase II trial using interleukin-2 (IL-2) by continuous infusion and alpha interferon (IFN) subcutaneously in 267 patients with a variety of advanced cancers, including 29 with breast cancer, 89 with renal cancer, and 69 with melanoma. IL-2 [18 million international units (MIU)/m2] was given by continuous infusion for 108 hours with 3 mu/m2 subcutaneous IFN every other day during the IL-2 infusion. The patients were treated for 1 week followed by a 2-week rest. After two cycles of treatment, patients were evaluated for response. Of the 237 patients evaluable for response, 20 (8%) had a complete or partial response and 128 (54%) were stable. Therefore, 62% of the evaluable patients were nonprogressive during the first 90 days of IL-2/IFN therapy. The objective response rate was 11% in melanoma, 7% in renal cancer, 14% in breast cancer, and 3% in patients with a variety of malignancies for an overall response rate of 7% in these patients with advanced cancer. The patients were treated on a general medical ward and tolerated treatment well with fatigue and fever being nearly universal. Dyspnea, pruritus, chills, and elevated creatinines were frequent but less common. This combination biotherapy regimen has minimal activity in a variety of advanced cancers and must be compared with the best existing chemotherapy for each cancer type in randomized, prospective trials.

Fifteen patients with advanced, measurable renal cell carcinoma entered a Phase II clinical trial of interleukin-2 (IL-2) (Teceleukin, Hoffmann-La Roche Inc., Nutley, NJ) and interferon (IFN) (Roferon A, Hoffmann-La Roche Inc.). IL-2 was administered by continuous infusion daily for 4 days and IFN was administered by intramuscular injection daily for 4 days; therapy continued for 4 weeks. Eight men and seven women were treated in this trial (median age, 61 years). Toxicity was moderate to severe with fatigue, nausea, vomiting, hypotension, and elevated blood urea nitrogen bunion and creatinine levels seen in all patients. Two patients achieved a complete remission and two patients achieved a partial remission. The median duration of response was 18 months. IL-2 and IFN is an active combination in the treatment of renal cell carcinoma and warrants further investigation.

Kaposi's sarcoma (KS) is a malignant neoplasm that develops in 20% to 30% of all acquired immunodeficiency syndrome (AIDS) cases. Kaposi's sarcoma primarily involves the skin, but can progress to involve the lungs, gastrointestinal tract, and liver. alpha-Interferon alone or in combination with zivoduvine has activity in acquired immunodeficiency syndrome-related KS, especially in patients with limited disease and CD4 lymphocyte counts over 400/mm3. Patients with progressive or symptomatic visceral disease, however, can be treated more effectively with cytotoxic chemotherapy. We have used a combination of doxorubicin, bleomycin, and vincristine (ABV) and have achieved response rates of over 80%. Discontinuation of therapy, however, is associated with relapse shortly after response (2 to 3 months). Thus, we have begun studies to define a safe and effective maintenance therapy. Such therapies should include antiretroviral agents since most patients succumb to other human immunodeficiency virus complications, and since human immunodeficiency virus directly, through viral proteins, and indirectly, through the induction of cellular genes, induces KS growth. Additionally, agents with antitumor activity and possible antiviral activity, such as alpha-interferon, may be potentially effective in maintenance therapies. We recently studied 21 patients in a phase I study of recombinant interferon alpha-2b (INTRON-A, Schering-Plough Corp, Kenilworth, NJ) alone following ABV chemotherapy. A dose of 10 million units, given in daily subcutaneous injections, was the maximal tolerated dose; higher doses were associated with intolerable fatigue, diarrhea, and fevers. We are currently conducting a phase I/II trial studying the combination of zivoduvine (500 mg/d) and recombinant interferon alpha-2b (5, 10, and 15 million units) as maintenance in patients with advanced or progressive KS.

Seventeen patients with malignant carcinoid tumour, ten of whom had the malignant carcinoid syndrome, were treated with recombinant alpha-2b interferon by subcutaneous injection (3 MU per dose) three times per week for a median of 12 weeks (range 4-48). No objective tumour responses were observed; however, there was a greater than 50% reduction in 24-hour urinary 5-hydroxyindolacetic acid (5-HIAA) excretion in four of ten patients (40%) with elevated pretreatment levels. Five of ten patients (50%) with flushing, five of seven patients (71%) with diarrhoea and both patients with wheezing experienced relief of symptoms. Three of four patients (75%) with weight loss as their only problem experienced weight gain. Responses occurred within the first eight weeks of treatment, but were generally of short duration. Toxicity occurred in all patients, and consisted mainly of fever, chills, anorexia, fatigue and weight loss. Four patients ceased therapy due to toxic reactions. Although interferon has activity against carcinoid tumours, its benefits are short-lived and toxicity limits its use with increasing dose. Patients with carcinoid syndrome appear to achieve the best therapeutic response, and it is likely that low doses (9-20 million IU weekly) are as effective as higher doses (36-72 million IU weekly).

A Phase II clinical trial of the combination of 5-fluorouracil (5-FU) and recombinant alpha-2a-interferon (alpha-2a-IFN) was conducted in 44 patients. Patients had not received chemotherapy previously and had measurable metastatic gastric carcinoma. 5-FU was administered as a continuous infusion at a dose of 750 mg/m2/d for 5 consecutive days and as an intravenous bolus at a dose of 750 mg/m2 weekly for 7 weeks beginning on day 12. Recombinant alpha-2a-IFN was administered subcutaneously at a dose of 9 x 10(6) U three times a week during weeks 1 to 8. Patients were examined for response during week 9. Of 44 patients entered, 40 could be examined for response. Nine patients experienced a partial clinical response and one achieved a complete response, for an overall response rate of 25% (95% confidence interval, 13% to 41%). The median duration of response was 13 weeks (range, 9 to 67 weeks) and the median survival time was 29 weeks. Grade 3 to 4 toxicities included granulocytopenia (nine patients), diarrhea (three patients), oral mucositis (seven patients), skin rash (one patient), and fatigue (four patients). One patient died of neutropenic sepsis. This regimen had modest activity with significant toxicity and produced responses of short duration. It did not appear to be superior to existing treatments of metastatic gastric carcinoma.

Nine consecutive patients with HCL seen over a period of five years were reviewed. Male: Female ratio was 8:1. Median age at diagnosis was 49 years. Weakness and fatigue (66%) were the commonest presenting symptoms and splenomegaly (66%) was the commonest physical findings. Varying degrees of pancytopenia was the consistent feature in majority of cases. Diagnosis was made on the basis of bone marrow biopsy and characteristic EM picture. Forty-four percent of cases developed serious infection during their clinical course. Gram negative bacilli and fungi were the most frequently isolated organisms. Major sites of infections were pneumonia and septicemia. Splenectomy was carried out in four cases. Rapid recovery of haematological parameters without any significant complication was observed in all these cases. Two patients were treated with alfa-interferon. In both the cases recovery of haematological parameters was slow compared to those under going splenectomy. One patient treated with alfa-interferon died due to infection related complications while the other went into remission.

The present trial was designed to evaluate whether interferon (IFN) combined with standard induction chemotherapy and/or interferon remission maintenance treatment improve treatment results in patients with multiple myeloma. Up to now 89 patients have received IFN plus vincristine/melphalan/cyclophosphamide/prednisolone (VMCP) as induction therapy, and 86 conventional VMCP. The proportion of patients with progressive disease was significantly lower (P less than 0.005) under IFN + VMCP as compared to the VMCP treatment group. Survival times were significantly longer (P less than 0.02) after IFN + VMCP induction therapy than after VMCP alone. In the second phase of this investigation, 33 progression-free myeloma patients were assigned to receive IFN as maintenance therapy, and 41 patients served as untreated controls. Patients maintained with IFN showed a tendency towards increased progression-free survival. Haematological side effects were observed significantly more often in patients receiving IFN, with more severe haematological toxicity in patients on the combined IFN + VMCP regimen and an increased number of patients with mild haematological toxicity in the group maintained with IFN. Other side effects, such as fever and fatigue, remained within tolerable limits. In conclusion, the preliminary results of this current clinical trial indicate significant advantages of combined IFN + VMCP induction treatment in terms of reduced disease progression and prolonged survival and possible benefits of IFN maintenance therapy in patients with multiple myeloma.

We evaluated clinical efficacy and tolerability of recombinant alpha 2a interferon (IFN), in a group of 16 patients with AIDS and ARC, including 3 children. All patients were followed up monthly for clinical and immunological studies. The frequency of oportunistic infections (OI) in AIDS, and the following symptoms in all patients were studied: fever, night sweats, fatigue, diarrhoea, weight loss. Immunological parameters (CD3+, CD4+, CD8+ lymphocytes, skin tests to recall antigens, NK activity, lymphoproliferative response to PHA) were also evaluated. Adult patients were treated with 3-6 million IU of r-alpha 2a IFN daily im for 3 months and the 3 times weekly up to 12 months. Pediatric cases were treated with lower doses of 0.5-1.5 million IU using the same time schedule. We observed clinical improvement and reduction of severe infections in 10/15 evaluable patients (4/4 ARC and 6/11 AIDS). Immunological parameters were transiently improved in one third of cases. We observed only mild side effects in r-alpha IFN treatment. We suggest therapy with r-alpha 2a IFN at low dosage should be tried in patients with AIDS for its beneficial effects on OI development.

Malignant carcinoid tumours with the carcinoid syndrome has over the years presented a therapeutic challenge. The patients might not only die from tumour progression but also from symptoms relating to hormone overproduction and the specific cardiac disease, e.g. right heart fibrosis and failure. Surgery has been the treatment of choice in local disease, but when liver metastases have developed other treatment procedures must be considered. Conventional chemotherapy has been of little beneficial value, with response rates of only 10-30%, whereas a new somatostatin analogue, octreotid, is effective in controlling clinical symptoms but not tumour progression. Interferon treatment was introduced in 1982 by our group, and we are now presenting treatment results of 130 patients with histologically verified malignant carcinoid tumours and liver metastases. One hundred and eleven patients were treated with a median dose of 6 mega units (MU) of interferon alpha, five times weekly (dose range 3-9 MU), whereas 29 patients received conventional chemotherapy. Forty-seven out of 111 patients (42%) treated with interferon alpha demonstrated a significant biochemical response and 15% demonstrated more than 50% reduction in tumour size. In another 43 (39%) patients stabilization of the carcinoid disease have been noted, whereas 21 (19%) showed progressive disease. The median duration of response was 34 months. Subjective responses with improvement of diarrhoea, flush and/or bronchoconstriction were noticed in 76 patients (68%). The 19 patients treated with chemotherapy demonstrated only 10% biochemical response, lasting for only 3-5 months. The survival analysis demonstrates a median survival of only 8 months in the group of patients treated with chemotherapy, compared to 80+ months (P less than 0.001) in the groups treated with interferon alpha. Interferon adverse reactions of fatigue, weight loss and anaemia were manageable. Neutralizing interferon antibodies were documented in 5-15% of the patients. Interferon alphas are active in patients with malignant carcinoid tumours. Clinical symptoms are significantly reduced following reduction of circulating hormones. Interferon might also have an impact on survival in this group of patients. The side-effects are moderate and managed by dose adjustments.
